"I am not a master of the klane; there is no living master of the klane. But I can teach you something of the way it may be used as a tool and a weapon", Crinomu said to Asanka. They began to train; Crinomu demonstrating the functions of the klane and then wielding a museum piece of a sword from classical Earth history to partner the youth as he practiced with the incomparably more complex instrument. "Within the handle there is a stabilized free quark resonance battery which draws from the raw potential of vacuum zero point energy, bleeding back very slowly what was stolen from the dark energy fields in a shattering instant in the quantal forge where it was fashioned. The klane does not really have an infinite energy supply but at the maximum rate of power the frequency flow allows you might as well consider it infinite for all practical purposes." The klane felt slightly warm and firm in Asanka's hand and seemed to dance with the intent of his muscles as if it knew where he wanted it to go next. He imagined that he could feel the hidden energies flowing through it; light and sharp and sparkling with the joy of action after its long sleep. "Around the handle is a quadruple switch gauge which controls the modality of the klane; the shape, strength and radius of the fields which it can deploy from the blade as well as the flow of energy to the blade, the spin, heat and fluxion currents. The knight wanderers had elaborate formal conventions within their duals about the accepted modes which may honourably be matched to one another and much was written about the lore of klane choreography - the sequences of customary attack and defence. You certainly don't need to worry about such arcane niceties even if I knew them myself (which I don't)." "We'll start with just one very important rule. Rotate the black tooth on the fourth gauge five clicks to the left of that thin top spline line and depress it into the barrel so that the forces are muted to training levels. I don't want any accidents whilst we're having these mock battles!"
